Abstract
The utility model discloses a kind of semi-insulating ring main unit segmentation cabinet current transformer device, comprise housing, it is characterized in that: also comprise current transformer module, installation module; Described current transformer module comprises mounting panel and is arranged on 3 current transformers on described mounting panel side by side; The corresponding described current transformer of described installation module is fixed on described case inside, comprises fixed head and is arranged on the insulator on fixed head; Described housing front compatibility installs described current transformer module.After its scheme realizes, its withstand voltage level of 10KV scheme reaches 42KV, and the safe and effective operation of support equipment.By the redesign to housing, increase design instrument transformer installation module, make device mounting means summary, eliminate fault point, and reach the modularization of parts, it is more convenient to change.High impetus is had for raising stable equipment operation.
Description
Technical field
The utility model belongs to controller switching equipment, particularly relates to a kind of semi-insulating ring main unit segmentation cabinet current transformer device.
Background technology
Along with socioeconomic development and scientific and technical raising, the stable operation of the controller switching equipment of power industry requires more and more higher.State's net requires that the normal service life of controller switching equipment reaches 30 years, and functional node is complete, stable, structure simple, modularization becomes inevitable path, in order to actively promote and respond the requirement of state's net, so that realize above-mentioned requirements on product, under the prerequisite ensureing product quality, realize parts summary, modularization becomes very urgent problem.
In prior art, the segmentation cabinet of semi-insulating ring main unit, due to structural limitations, uses straight-through current transformer, finds that its withstand voltage level is unstable, easily electric discharge phenomena occur in operation.Cause equipment to break down, there will be severe short circuit accident.Can not meet the related request of Guo Wang company for stable equipment operation, and segmentation cabinet adopts copper bar to connect, after instrument transformer breaks down, 3 independent instrument transformer dismounting difficulties of installing, are not easy to timely replacing during repairing.
Summary of the invention
For prior art Problems existing, the present invention proposes a kind of semi-insulating ring main unit segmentation cabinet current transformer erecting device, has substitution effect.
The present invention proposes a kind of bushing current transformer device meeting segmentation cabinet and use, and after its scheme realizes, its withstand voltage level of 10KV scheme reaches 42KV.By customizing special wall bushing formula current transformer, improve the withstand voltage level of instrument transformer, by the redesign to cabinet, 3 instrument transformers are installed on a mounting board, form modular current transformer module, make itself and housing compatibility, reach modular requirement.
A kind of semi-insulating ring main unit segmentation cabinet current transformer device, comprises housing, it is characterized in that: also comprise current transformer module, installation module; Described current transformer module comprises mounting panel and is arranged on 3 current transformers on described mounting panel side by side; The corresponding described current transformer of described installation module is fixed on described case inside, comprises fixed head and is arranged on the insulator on fixed head; Described housing front compatibility installs described current transformer module.
Device sheet metal member, comprises the bending strength >=170MPa such as housing, mounting panel, fixed head; Described current transformer is wall bushing formula.I.e. external shell bending strength >=170MPa.
Local discharging level≤10pC under local discharging level under current transformer module secondary outlet terminal 1.2Um≤20pC, 1.2Um/ √ 3.Rated voltage 12KV, specified power frequency 1min withstand voltage (alternate and to mutually ground) >=42KV.Rated voltage 12KV, rated lightning impulse withstand voltage peak value (1.2/50 μ s) (alternate and to mutually ground) >=75KV.Device for mechanical stability >=5000, component end item interchangeability 100%.
The advantage that the utility model compared with prior art has is: increase installation module and original instrument transformer is changed into wall bushing formula, not only solving problem of withstand voltage also makes layout more reasonable, improve the withstand voltage level of instrument transformer, and the safe and effective operation of support equipment.By the redesign to housing, increase design instrument transformer installation module, make device mounting means summary, eliminate fault point, and reach the modularization of parts, it is more convenient to change.High impetus is had for raising stable equipment operation.
